[fw-general] Zend_Cache_Frontend_Page bug. stable and snapshot

[Кононов Руслан]

I'm create simple application for testing Zend_Cache_Frontend_Page, but 
nothing work!!!
No debug header, no data in cache dir, no exceptions.

Now I,m check Zend source and found bug in _makeId() function.

line 258 of Zend\Cache\Frontend\Page.php

written :
if ($tmp2===false) {
              return false;
 }


need use 'continue';

Please, fix it!
